Abstract

A computer-implemented method of operating a diabetes treatment system that includes an insulin pump and a pump controlling device is disclosed. The method includes receiving, by the device, a request for the pump to perform an operation that is dependent on a specified state of the pump. The method also includes requesting, by the device, a current state of the pump from the pump. Moreover, the method includes receiving, by the device, the current state of the pump. Also, the method includes determining, by the device, whether the current state of the pump matches to the specified state of the pump. Additionally, the method includes sending, by the device to the pump, a command to perform the operation in response to a determination that the current state of the pump matches the specified state of the pump.

       2. The method of  claim 1 , wherein performing the corrective action includes sending, by the pump controlling device to the insulin pump, a command to change the current state of the insulin pump to the specified state of the pump. 
     
     
       3. The method of  claim 1 , wherein the insulin pump has a run state and at least one of a pause state and a stop state, wherein the request to perform an operation is a request for the insulin pump to start insulin delivery, wherein starting insulin delivery is dependent on the insulin pump currently being in the at least one of the pause state and the stop state, wherein sending the command to start insulin delivery occurs in response to a determination that the current state of the insulin pump is the at least one of the pause state and the stop state. 
     
     
       4. The method of  claim 1 , wherein the insulin pump has a run state and at least one of a pause state and a stop state, wherein the request to perform an operation is a request for the insulin pump to activate a temporary basal rate of delivery of insulin, wherein activating the temporary basal rate is dependent on the insulin pump currently being in a run state, and wherein sending the command to activate the temporary basal rate occurs in response to a determination that the current state of the insulin pump is in the run state. 
     
     
       5. The method of  claim 1 , further comprising requesting, by the pump controlling device from the insulin pump, an execution result of sending the command to perform the operation.
